AbstractCharacteristics of oxide films formed on 304 (UNS S30400) stainless steel during crevice corrosion in 290 degrees C pure water have been investigated. It was found that the oxide films were different at different sites along the crevice. Decreased dissolved oxygen within the crevice resulted in a potential gradient. Such a potential drop affected the development of oxide films. The lamellar oxide near the crevice mouth was mainly FeCr2O4. The regular oxide far from the crevice mouth was mainly Fe3O4. Possible mechanisms of crevice corrosion and growth of the oxide films at different sites in high-temperature water are also discussed.
